It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, Allah Almighty boasts of the people of Arafat before the people of the heavens, that is, the angels, and says: Look at these servants of Mine; they have come dishevelled and covered in dust."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Mujahid except Yunus bin Abi Ishaq."
